The aim of the course is to provide students with a basic understanding and concepts of control systems. The course starts by introducing basic concepts of feedback control systems using a number of practical examples. Mathematical modelling of physical systems and representing them in block diagrams with transfer functions are presented. Basic control system response characteristics (stability, transient response, steady state response) and analysis and design procedures are introduced using first and second order systems. Analysis of control systems using Routh-Hurwitz criterion, root locus, and Bode plot methods are considered.
